I´m wondering how fast 9800 GX2 is compared to GTX 260 or GTX 275.
there's a chart on the folding forum, I cant remember where it is, but it's there. it's not rock solid accurate, just numbers users reported. so I never really bothered with it.
the gx2 is gonna be more ppd because it has 2 128sp cores and can run 2 clients. but my last one was so dam hot, I got rid of it. like 90-110c on the hotter wu's. the single core 200 series cards arun a lot cooler, like 60's and 70's..
the best rule of thumb is fahgpu client scales with shader sp count on the nvidia side.
gx2 has 2 cores of 128 sp's... (256 total sp's)
gtx260 has one core 192 or 216sp's
gtx275 has one core 240sp's.
it's hard to put a ppd number in type on the forum. the wu's turn different points. someone says "Oh my gtx260 does 8000ppd, then another user says my gtx260 does 4500ppd". that's because they were on different wu's. if all the wu's were the same, then we could use ppd as a good comaprison, but the backwards a$$ way Pande benches all the wu's on a ati 3850 to determine points value of each wu makes uising ppd as a comaprison on nvidia cards a useless venture.. unless you are comparing exact wu to wu on the same project. it's stupid, but what we're stuck with from PG.
when your'e determing you're folding card purchase, your best bet is to.
1. Maximize shader count.
2. while at the same time balance it with user needs.
(the higher end 240sp cards are power suckers, except for the 55nm 285) and (the dual core cards are heat monsters).
but those last 2 depend on you.
-do you care about power, or have a beefy a$$ psu already if you're gonna run dual or triple card rig.
-is heat even a consideration, like are you gonna just WC them anyway.
anyway, that should put it in a nutshell.. personally I like the gtx260 216's... cool running, affordable, not a power hawg, and good production. or the 285 if money is not an issue.
main reason I have 250's in my dual card rigs in my sig, is because I didn't feel like spending a bunch of money on 4 gtx260's as well as new psu's. the 250's were cheaper and I could keep my existing psu's to power the dual cards.
in the end it's a customized decision based on your current needs as a user. not really about what card does the most.
My GX2's vary from about 3800 to about 6800 per side depending on the WU's and the overclock (lesser overclock in summer cos they get really hot) and this is with ambients that normally stay between 0deg C and 30deg C max where I live (well ventilated outbuilding) The average is probably around 9500-10500ppd per GX2

(Thinks....must remember to punctuate)
I carpeted my dog house...It now has windows too so when my crunching generates heat. My dog house has AC, wifey's house doesn't...:rofl:
Dak's doghouse also has a fully stocked bar and ice machine...
Well duh...Kinda like saying "my dog has paws"....Don't all doghouse's have fully stocked liquor & Ice machine...Let's not be cruel to our animals please.:ROTF:
check one of my recent vga reviews on techpowerup. folding performance is part of our test suite
That's what I use. Found nothing better. :up:Quote:

Others may have suggestions but yours works for me.
now that you mention it. How do you get around the wu type dilemma when publishing your performance report? if it's not the same wu, then there is no control group in the data published to produce comparable results between cards; or cores if the card is a dual core card on 2 clients. DO you even ppd bench the dual core cards on 2 clients for combined ppd? or is it just whatever wu's were available when the card is tested? if that's the case, then the data is just a snapshot and the cards' data are completely independent of each other and not comparable as a performance bench other than being a individual isolated ppd number for that individual wu and clone in time and scope of the fah project (which changes over time anyway (what wu's are available today, are not available a month from now).Quote:

here's one of our old ppd threads...

PG needs a standard benching mechanism like boinc has to overcome this dilemma. until they have it, these performance benches really dont give anyoone comparable data. it's the same concept as someone running a crysis bench and then using that data to determine how it will perform in all games. you just can't make that assumption with any degree of certainty because a bench in crysis will not automatically apply to all games.

For those that haven't seen Wizard's efforts at Techpowerup...

that's still a good ranking though, except for the 2 dual core cards. They're out of place because they were benched on one core, not both. so multiply the GX2 and the gtx295 ppd x2 and move them to the end of the list and it's a pretty accurate ranking, just ignore the ppd numbers and number them lowest to highest production.
main reason I dont like the dual core cards is heat. for me, my gx2 heat experience ruined the high ppd experience for the card. the back of that pc case felt like an oven window while it was left folding 24/7... plus it really messed my hall ac thermostat up, all the heat from that little office spilled into the hall and screwed up the thermostat something fierce. a dual core 100c gpu on 100% fan 24/7 will do that I guess.
